Brothers (A One Direction Spanking Story!)

Liam Zayn Niall and Harry are brothers who's parents died in a tragic car accident. Liam and Zayn, who were 19 at the time, became their gardians, and in order to keep the younger boys in line they spank them.
Louis Tomlinson. A 14 year old homeless kid, who's parents were abusive and are the reason for him being on the streets depressed and angry.
Louis doesn't think that love exists, he believes that everyone is out to hurt you, so he simply doesn't let anyone in.
When the boys find him, can they change that?
